18119226 divided by 604 
The aim is to understand the frequency of 604 in 18119226.

On to step 1:
When dividing 1 by 604, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 604

Let's proceed to step 2:
The number 604 fits into 18 0 times, leaving a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 18 after subtracting 0 from 18.
Fetch the next digit (1) from the dividend, attach it to 18 and continue: 181 / 604

Step 3:
604 goes into 181 0 times with a remainder of 181.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 181, we end up with 181.
Append the next digit (1) from the dividend to 181 and continue with: 1811 / 604

Advancing to step 4:
1811 divided by 604 is 2 with a remainder of 603.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 1208 from 1811 to get 603.
Fetch the next digit (9) from the dividend, attach it to 603 and continue: 6039 / 604

Moving on to step 5:
604 can be fit into 6039 9 times, resulting in a remainder of 603.
Record the quotient 9 as the next digit in the result. 
Result so far: 29.0
If we take 5436 away from 6039, we end up with 603.
Grab the next digit (2) from the dividend, add it to 603, then carry on: 6032 / 604

Moving on to step 6:
The number 604 fits into 6032 9 times, leaving a remainder of 596.
The next digit of our result is 9. 
Result so far: 299.0
Subtracting 5436 from 6032 leaves us with 596.
Fetch the next digit (2) from the dividend, attach it to 596 and continue: 5962 / 604

Going ahead to step 7:
5962 divided by 604 is 9 with a remainder of 526.
The number 9 becomes the next digit in our result. 
Result so far: 2999.0
If we subtract 5436 from 5962, we get 526.
Include the next digit (6) from the dividend after 526, then repeat: 5266 / 604

Advancing to step 8:
5266 divided by 604 is 8 with a remainder of 434.
Use 8 as the next digit of our solution. 
Result so far: 29998.0
Deduct 4832 from 5266 and we're left with 434.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4340, and continue the process.

Let's proceed to step 9:
604 goes into 4340 7 times with a remainder of 112.
The number 7 becomes the next digit in our result. 
Result so far: 29998.7
Subtract 4228 from 4340 to get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Let's proceed to step 10:
604 can be fit into 1120 1 times, resulting in a remainder of 516.
The next digit of our result is 1. 
Result so far: 29998.71
The remainder is 516 after subtracting 604 from 1120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

On to step 11:
604 goes into 5160 8 times with a remainder of 328.
Put 8 as the next digit of the answer. 
Result so far: 29998.718
The remainder is 328 after subtracting 4832 from 5160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Advancing to step 12:
604 can be fit into 3280 5 times, resulting in a remainder of 260.
The number 5 becomes the next digit in our result. 
Result so far: 29998.7185
The remainder is 260 after subtracting 3020 from 3280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Step 13:
The number 604 fits into 2600 4 times, leaving a remainder of 184.
Record the quotient 4 as the next digit in the result. 
Result so far: 29998.71854
Deduct 2416 from 2600 and we're left with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Advancing to step 14:
When dividing 1840 by 604, we get 3 with a remainder of 28.
The number 3 becomes the next digit in our result. 
Result so far: 29998.718543
The remainder is 28 after subtracting 1812 from 1840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 15:
604 can be fit into 280 0 times, resulting in a remainder of 280.
The next digit of our result is 0. 
Result so far: 29998.718543
If we subtract 0 from 280, we get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Going ahead to step 16:
The number 604 fits into 2800 4 times, leaving a remainder of 384.
Put 4 as the next digit of the answer. 
Result so far: 29998.71854304
Subtracting 2416 from 2800 leaves us with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

The final outcome is 29998.71854304, with a leftover of 3.84e-07.
